Problems solved by technology

[0003] Highly transparent polycarbonates and the like are known as transparent resins for optical applications. However, heat resistance and mechanical strength are problematic when used in the manufacture of display elements.
On the other hand, polyimides can be cited as heat-resistant resins. However, general polyimides are colored dark brown, so there is a problem in optical applications. In addition, as transparent polyimides , a polyimide having a ring structure is known, however, it has a problem of lowering heat resistance

Abstract

Provided, in one or more embodiments, is a polyamide solution which is capable of suppressing whitening when applied to a glass substrate. In one aspect, the present invention relates to a polyamide solution which comprises an aromatic polyamide and an amphiphilic solvent. In other aspects, the present invention relates to a polyamide solution which comprises an aromatic polyamide, an amphiphilic solvent, and an aprotic polar solvent. In other aspects, the present invention relates to an aromatic polyamide solution for producing a display element, optical element or lighting element.

Description

technical field [0001] In one aspect, the present invention relates to a polyamide solution containing an aromatic polyamide and an amphiphilic solvent, which is used in the production of display elements, optical elements, or lighting elements. In another aspect, the present invention relates to a laminated composite material including a glass plate and a polyamide resin layer, and a polyamide resin layer formed using the polyamide solution described above is laminated on one surface of the glass plate. In another aspect, the present invention relates to a method for producing a display element, an optical element, or a lighting element, which includes the step of forming a polyamide film using the above-mentioned polyamide solution. Background technique [0002] Transparency is required for the element for a display, and therefore, as the substrate, a glass substrate using a glass plate is used (Patent Document 1). However, there are cases in which problems such as heavy ...
